I tried your suggestion in
dhtmlx.com/docs/products/kb/inde … 13&a=12904
but it didn’t work.
It produced an error of “this.con is null” at line 51 of dhtmlxcalendar.js.
Not only did the new calendar not appear, but also the cloned row itself did not appear.
Hello,
such an error can occur if you try to initialize calendar in the non-existent container. Please, check that containers with ‘DATE0’ + newRowCount ids are created.
